       1. A container comprising a bottom wall, at least one wall projecting upwardly from said bottom wall to define a cavity, said at least one wall comprising at least two oppositely disposed side portions, a flange projecting outwardly from said wall, said flange having reinforcing means secured thereto at said side portions, a cover member comprising an outer edge flange integral with an inner countersunk portion disposed in a different plane than said outer edge flange and connected thereto by a substantially vertical portion, said reinforcing means being so constructed that it extends inwardly from said wall into said cavity to receive and lock in place said cover member in sealing relationship to said container, and said countersunk portin and said substantially vertical portion cooperating with said reinforcing means to lock said cover member in sealing relationship to said container. 
     
     
       2. The container of claim 1, wherein said reinforcing means is integral with said flange at at least one of said side portions. 
     
     
       3. The container of claim 1, wherein there are four walls projecting upwardly from said bottom wall arranged in such a manner that they define a rectangular cross-section. 
     
     
       4. The container of claim 3, wherein said flange extends around the entire perimeter of said container. 
     
     
       5. The container of claim 4, wherein said reinforcing means extend around the entire length of said flange. 
     
     
       6. The container of claim 3, wherein said reinforcing means comprises two side members secured to said flange and said side portions and said members extend around the corners of said container. 
     
     
       7. The container of claim 1 wherein said flange is integral with and folded along the upper edge of said wall.
